Ceramsite concrete self-insulating exterior wall panel and manufacturing method thereof

Abstract

The invention discloses a ceramsite concrete self-insulation external wall panel and aims at providing a ceramsite concrete self-insulation external wall panel which is stable and firm in structure and good in heat preservation performance. According to the technical scheme, the ceramsite concrete self-insulation external wall panel is characterized by comprising a ceramsite concrete layer and a reinforcing steel bar net rack arranged in the ceramsite concrete layer; the reinforcing steel bar net rack comprises an upper net piece and a lower net piece; the reinforcing steel bar net rack is provided with a plurality of reinforcing steel bars, the two ends of each reinforcing steel bar are connected with the upper net piece and the lower net piece respectively, and the reinforcing steel bars are distributed in the thickness direction of the ceramsite concrete layer; the ceramsite concrete layer is provided with a plurality of pre-buried sleeves, and a plurality of reinforcing steel bars are distributed at the positions where the pre-buried sleeves are arranged in the ceramsite concrete layer. The structural strength is large, a hot and cold bridge effect does not exist, and by means of cooperation of the pre-buried sleeves and the reinforcing steel bars, restraint on the ceramsite concrete around the pre-buried sleeves is enhanced, and the anti-cracking and anti-shearing performances of the ceramsite concrete self-insulation external wall panel are improved.

Description

technical field [0001] The invention relates to a wallboard, more specifically to a ceramsite concrete self-insulating exterior wallboard. Background technique [0002] The development of construction industrialization not only requires the construction industry to undergo industrial structural transformation and advance towards fine manufacturing. For concrete engineering, a large number of prefabricated components will be used to form different structural forms of assembled wholes through reliable connections. At present, the main prefabricated components are prefabricated columns, laminated beam slabs, shear walls, external wall panels, internal partition wall panels, stairs, balcony panels and even integral kitchen and bathroom, etc. Among them, the prefabricated external wall panels are mainly directly related to building energy conservation. They should meet the thermal performance requirements while meeting the thermal insulation requirements. Of course, they must al...

Problems solved by technology

However, no matter which form of connection is adopted, the integrity of the sandwich insulation layer will be destroyed to a large extent, because the connector or the steel truss must pass through the insulation layer, especially the damage of the steel truss is caused by the nature of the section, so As a result, a "thermal bridge" phenomenon will naturally be formed, and the insulation effect of the insulation layer will be greatly affected.

[0004] At the same time, this type of connection, especially the steel truss, needs to pass through the insulation layer repeatedly during construction, which makes the construction very troublesome and the quality cannot be guaranteed.

Moreover, the density of these two materials is very different, and it is difficult to melt during the forming process, resulting in a large deviation in the thickness of the inner and outer blades during the vibration flow, that is, it is difficult to ensure the quality of the finished product, and it is easy to cause quality accidents
